Version 1.0 (October 2016) Page 1

DEFINITIONS

District Metered Area (DMA)

A small metered area within a supply and distribution system that is specifically defined, for example by the closure of valves. The quantity of water entering and leaving the area can be metered permanently. Also referred to as a Demand Management Area.

Estate Maintenance and Operational Services (EMOS)

Defence Contractor responsible for the maintenance of the estate, including the location, maintenance and operation of Defence meters and metering systems.

Gate meter Defence owned meter immediately downstream of the utility meter measuring the site’s resource consumption.

Metering System Refers to a resource monitoring system at the facility/building level (e.g. Building Management System (BMS)) or precinct/site/regional level system (e.g. Regional Utility Management System (RUMS)).

New Build Activities that involve the installation and connection of new meters and/or metering system hardware/software (e.g. BMS) during the construction of new facilities, infrastructure or equipment.

National Sub-meter Program (NSP)

Defence’s metering, monitoring and management program in response to the Commonwealth Government’s Energy Efficiency in Government Operations (EEGO) policy. The collected data is organised within Defence’s Resource Management System (RDMS).

NSP Program Manager Person responsible for managing the NSP, reporting against Program KPIs, and ensuring the installed meters and metering systems are connected to the RDMS.

Parent and child meters

Sub-meters where the parent meter is upstream of the child meter and measures the child meter’s consumption in addition to other streams. It is important to understand the relationship between meters to avoid double counting. This information is collected through the Meter Hierarchy Template.

Project Delivery Service (PDS)

Defence Contractor responsible for managing the tendering and installation of meters and metering systems under Defence’s Estate Works Program.

Program Sponsor Defence authority responsible for overseeing the NSP such that the program objectives are realised. The sponsor is the Directorate of Energy Efficiency, Environmental Resource Management and Sustainability (DEEERMS).

Resource Data Management System (RDMS)

A network of meters measuring Defence’s electricity, water and gas consumption and transmitting this data to a central data repository allowing users to report, analyse, investigate and action resource opportunities.

Refurbishment Activities that involve the installation and connection of new meters and/or metering system hardware/software (e.g. Building Management System) during the repair or replacement of existing facilities, infrastructure, systems and equipment.

Retrofit Activities that involve the installation, reconfiguration and/or connection of meter and/or metering system hardware/software to existing facilities or infrastructure. In the NSP context, retrofit installations are those that occur outside of the delivery of new or refurbished capital works.

Service Provider Responsible for planning and designing the installation and connection of meters and metering systems in accordance with the NSP requirements.

Sub-meter

Meter that measures a particular building/end use downstream of the utility gate meter and provides better granularity of resource usage. The majority of sub-meters connected to the NSP are measuring facility/building level resource consumption. There are some instances where sub-facility/building data is being captured under the NSP, primarily for the separation of ‘Light and Power’ and ‘Central Plant’ end uses in offices (Table 3-3).

Utility meter Meter that the utility reads to determine Defence’s utility charges often measured at the gate.

1. SECTION 1

1 PROGRAM OVERVIEW

1.1 Document Purpose The purpose of this document is to define the National Sub-meter Program (NSP) such that Defence can:

• make the purpose for the NSP clear to relevant stakeholders • detail the performance requirements against set key performance indicators (KPIs) and their

corresponding targets • apply consistent decision making when making investment decisions and prioritising program

investment • detail metering requirements to stakeholders.

1.2 Associated Documents This document should be read in conjunction with Defence’s Smart Infrastructure Manual: Design and Construction. An overall document matrix outlining how these documents fit into the NSP document suite is explained further on the Defence Estate Quality Management System (DEQMS).

1.3 Program Drivers 1.3.1 Government Policy The Government’s Energy Efficiency in Government Operations (EEGO) policy requires Defence to develop and implement a comprehensive energy management strategy that includes a metering, monitoring and management program. The NSP is designed to meet these EEGO requirements and define end use categories in accordance with EEGO (refer Table 3-6). The data captured under the NSP is organised within Defence’s Resource Management System (RDMS).

1.4 Defence Policy and Strategy The NSP is driven through Defence resource management policy and strategy, namely:

• Defence Estate Energy Policy (2014) • Defence Estate Water Policy (2014) • Defence Estate Energy Strategy (2014-2019) • Defence Estate Water Strategy (2014-2019)

A primary objective defined in both policies is: ‘Measuring and Monitoring – ensure infrastructure and processes are in place to be able to measure and manage Defences energy and water consumption and energy generation effectively.’

2. SECTION 2

2 PROGRAM IMPLEMENTATION Defence has identified four functions to achieve the National Sub-meter Program objectives defined in Section 1.5. These are:

1. NSP Program Manager 2. Software Platform 3. Data Acquisition 4. Governance.

The four functions are described below.

2.1 NSP Program Manager The NSP is overseen by the NSP Program Manager. The NSP Program Manager reports directly to the Program Sponsor. The NSP Program Manager is required for the ongoing development, implementation, and integration of the NSP into Defence’s day-to-day business. The NSP Program Manager drives the program such that a secure, useful and reliable NSP will meet the overall program objectives. The requirements of this role are defined in Section 2.5.

2.2 Software Platform The NSP Program Manager is responsible for the ongoing operation and maintenance of the software platform. The NSP is supported by a web-based software platform, compliant with Defence security requirements and receives data from NSP metering points across the estate. The data is stored and managed within the software platform in accordance with quality management and assurance processes outlined in the relevant program protocols. The software platform has the functionality to allow users to undertake data analysis and automated reporting to help meet users’ resource reporting requirements. The software platform, analysis and reporting functionality requirements are described in more detail in Section 2.5.

2.3 Data Acquisition The NSP Program Manager is responsible for the regular and secure acquisition of NSP Data, specifically that:

• Data is transferred from each installed NSP meter and NSP measurement device (e.g. individual electricity, water or gas meter or BMS) to the software platform on a regular basis (typically daily).

• Any data transfer that contains identifiable information is secure (i.e. an intercepted file should not allow the physical location to be matched to the metered data).

• The transfer has quality control protocols in place to ensure the completeness of the received information (i.e. no missing data).

Acquisition data requirements are described in more detail in Section 2.5.

2.4 Governance Governance of the NSP is the responsibility of the Program Sponsor on behalf of the Assistant Secretary Environment & Engineering (ASEE): Progress of the NSP is measured using the KPIs outlined in Table 1-2 and reported annually to ASEE. Program Governance requirements are outlined in Section 2.5.

3. SECTION 3

3 PLANNING AND DESIGN

3.1 Precedence There are multiple electricity, water and gas meters across the Defence estate. Meters and metering systems connected to Defence’s RDMS are for the purpose of national energy management and associated reporting. The remainder of the meter fleet has been installed in response to other requirements, external to the sub-meter program. These requirements are contained in the following:

• Section J Energy Efficiency of the National Construction Code (NCC) Volume One – Building Code of Australia (BCA)

• Defence Manual of Infrastructure Engineering – Electrical (MIEE).

The NSP requirements do not supersede these other metering requirements.

3.2 Requirements Service Providers responsible for planning and design activities shall ensure the following is undertaken:

• The planning and design of NSP electricity, water, and gas meters and metering systems is in accordance with the requirements outlined in Sections 3.3 to 3.6.

• Any new meter allocations are to be designed and installed in accordance with Defence’s Physical Security Zones (PSZ) methodology. Building users must be informed that the meters are wireless and these meters conform to the overall building classification. Details of the PSZ methodology is available via the DRN intranet here.

• The decision to connect a BMS to the RDMS is at the discretion of the NSP Program Manager in accordance with Section 3.5 and the BMS-RDMS Connection Protocol.

• Any new or replacement meters or BMS meet the relevant hardware and data protocol specifications available on the NSP page through DEQMS.

• For New Builds or Refurbishments the Service Provider submits to DEEERMS a final Metering Strategy and Metering Hierarchy Template at design completion. Both are available on DEQMS.

• For retrofitting meters to existing facilities, Service Providers submit a New Meter Form and Meter Hierarchy Template in accordance with the meter installation guideline (available from DEQMS) for any new meters or replacement meters being connected to the RDMS.

• New or replacement meters are added to Defence's estate information system to ensure maintenance of the meter hardware can be performed.

3.3 Program Exemption Where the NSP requirements cannot be met due to technical feasibility (e.g. prohibitive for safety or for security reasons) and/or not cost effective for Defence, then an exemption shall be sought with appropriate justification and supporting evidence (e.g. cost estimate to install the meter). Written Defence acknowledgement shall be obtained by the Service Provider at the initial design stages via [email protected]. Post-construction requests for exemptions are not acceptable.

3 Other generation systems will be revisited for inclusion in the future. 4 Under the Renewable Energy Target (RET) scheme generation systems have different capacity thresholds above which these systems are eligible for the creation of Large Generation Certificates (LGC) and must be metered to do so. Where LGCs will be created then metering in accordance with the relevant kW capacity threshold under the RET scheme takes precedence. 5 Significant refurbishments are those that can change the total building and services regulated annual energy consumption by more than 10%. The 10% limit applies to those staged refurbishments that occur over a 3 year period with no less than a 3 year period between one set of refurbishments and the next set. Refer to Defence’s BEPM for further detail. 6 Where the cost to connect to the RDMS becomes prohibitive or technically not feasible (e.g. safety or security reasons) then the facility shall be included under the targeted monitoring program in preference to the installation of direct connect or closed Current Transformer (CT).

a. L&P where estimated electricity consumption >100,000 kWh p.a.

b. Central Plant where estimated electricity consumption >100,000 kWh p.a.

The number of meters should be minimised while covering these categories, e.g. if building electricity usage is only Central Plant and L&P (and both > 100,000 kWh p.a.) a whole building meter is not required. Alternatively, a virtual meter may be provided as per the requirement outlined for ‘office buildings > 2,000m2’.

For mixed use buildings, provide a separate meter for each individual area, special load or category of consumption (e.g. workshop) where estimated electricity consumption > 100,000 kWh p.a. If more than 80% of the estimated electrical consumption can be attributed to a single category assign the building to this category.


Non-office buildings with estimated maximum demand >100 kW

One NSP meter to cover the whole building’s electricity consumption.

If more than 80% of the estimated electrical consumption can be attributed to a single category assign the building to this category.


Special cases

There may be special cases on new infrastructure or major refurbishment projects where additional NSP meters may be required, outside the conditions listed above. These will generally include buildings that exhibit large, short duration loads (kW/kVA demand) that have a significant impact on a sites power and energy (kWh) usage profile. Examples include priority operational loads such as ship degaussing, the provision of meters for on billing of third party electricity use and sites where load and consumption are needed to monitored closely for operational purposes (e.g. demand at site needs to be rationed throughout the day, load shedding).

If there is a likelihood that any buildings will be used by third parties these buildings shall be metered separately for the purpose of cost recovery by Defence.

In these cases NSP meters may also be specified by the Program Sponsor or Defence Representative (e.g. NSP Program Manager).

Retrofit

Group of similar non-office existing buildings with estimated aggregate electricity consumption >200,000 kWh

One NSP meter to cover an aggregated group of the same type of buildings with similar consumption profiles, where circuitry allows.

If there are any loads that will distort the typical profile then these buildings shall be metered separately, subject to the thresholds above.

If there is a likelihood that any buildings will be used by third parties these buildings shall be metered separately for the purpose of cost recovery by Defence.

Building categories under the NSP are detailed in Table 3-6.



The specific building/load type requirements and thresholds for water meters are summarised in Table 3-4 .

Table 3-4: Water meter thresholds

Building/load type NSP water metering requirement


Buildings with estimated water consumption >5,000 kL p.a.

One NSP meter to cover the infrastructure’s total water consumption and NSP meters to cover each of the following high priority end uses where estimated water consumption >5,000 kL p.a.:

a. Amenities water consumption (toilets, showers, basins).

b. HVAC water consumption (e.g. cooling towers).

c. Irrigation water consumption.

d. Process water consumption (e.g. operational equipment or use, wash points).

The number of meters should be minimised while covering these categories. If remaining building/area water consumption does not exceed 5,000 kL p.a. then no other NSP metering is required.


Water reticulation

The layout of new water reticulation shall be separated into distinct water supply areas (District Metering Area (DMA)) with the entrance and outlet (if applicable) metered to facilitate leak detection. The layout of the water reticulation network shall be designed to minimise the number of meters while maximising coverage and leak detection capability.


Water reticulation for irrigation

NSP meters shall be provided where the downstream estimated water consumption for irrigation >5,000 kL p.a. This threshold shall be used for each DMA within the irrigation network.

The layout of the water reticulation network shall be designed to minimise the number of meters while maximising coverage and leak detection capability.

The specific building/load type requirements and thresholds for gas meters are summarised in Table 3-5. Meters must have the capability and connectivity via a modem or other communication device to the RDMS.

Table 3-5: Gas meter thresholds

Building/load type NSP gas metering requirement


Buildings with estimated gas consumption >700 GJ p.a.

One NSP meter to cover infrastructure’s total gas consumption and NSP meters to cover each of the following high priority end uses with estimated gas consumption >700 GJ p.a.:

a. Water or air heating (swimming pools, DHW boilers, HVAC heating boilers, steam generation).

b. Different sections of a mixed facility e.g. workshop and office that meet the threshold where they have different gas consuming equipment.

c. Cogeneration.

The number of meters should be minimised while covering these categories. If remaining building/area gas consumption does not exceed 700 GJ p.a then no other NSP metering is required.



3.7 Sub-meter characterisation Each sub-meter installed as part of the NSP must be characterised according to the categories listed in Table 3-6. The Facility Group category is the high level category that Defence uses to report under Commonwealth EEGO requirements. Underneath each Facility Group there is a variety of Facility Type categories which will be used for internal Defence energy management activities, these are less formal and new options can be added as the program continues to evolve.
